What kind of time frame is there for fondant in the heat. Like 100 degree heat and humidity.
I have an outdoor festival to do in August and would really like to do at least on dummy. Two full days in the heat actually.
Should I just give up the idea of fondant and use the light wieght spackling?? I'm wantig to do the 4 tier wilton castle wedding cake.
Spackle removes almost all risk. For that much work, I would want a guarantee not to melt.
Fondant hardens over time. If you created the design a couple of days ahead of time and let it harden, there wouldn't be anything to melt. My bigger concern is going to be with bright colors fading. If you are in the shade you will be fine, but if you are in direct sunlight, bright colors fade very quickly. One of the worse offenders is the color red!
If it is a cake dummy and the fondant has had time to dry I am pretty sure fondant will be fine.
